I have an RBG and for everyday use I'm happy with it. It is not set up to do wavy blades very well, but is solid, well built, very good customer support and an OK price. The MAG is top of the line, I have one of their balancers, and while it is expensive, is great American technology and works GREAT. The MAG blade grinder however might be over priced, but some people luv em'.
